Approach Putting everything in its proper time and place

Provide sufficient time to develop a quality V6 product

exhibiting significant improvement over V5 Time allocated for:

Preliminary investigations,

prototyping and demonstration tests

Development time – greater than 1 year for development and test
Integration into AIRS PGE at JPL
Testing – six months allocated for comprehensive tests
Mid-course corrections, status checks at least two more Science

Team meetings (Fall 2007 [this meeting] and Spring 2008)

We are here We are here now! now!

Process

Concept Phase
Science Team is encouraged to develop new concepts approaches that will

result in significant improvements to AIRS products

CCB will move slowly – approving minimal changes to code base
Control changes to mitigate externalities
Development Phase
Prior to delivery, developer must demonstrate functionality and

effectiveness in working prototype

Science Team and AIRS Project will concur on significant changes
Developer must Demonstrate that code produces same (and

intended) results once integrated into a working prototype of the AIRS PGE at JPL in the AIRS development environment

Code does not cause adverse downstream effects
Integration and Test Phase
Tightly controlled code
CCB will not entertain new concepts, good ideas,

well intentioned improvements, …
